WebbWe have found that lower tidal volumes, which may actually worsen oxygenation and reduce clearance of CO 2, ... but a growing body of evidence suggests that the use of higher tidal volumes is harmful in patients with normal lungs undergoing general anesthesia or in patients with lung diseases other than ARDS requiring mechanical ventilation. Webb1 apr. 2024 · Low tidal volumes during 1-lung ventilation do not worsen oxygenation or compliance. A low tidal volume ventilation strategy during 1-lung ventilation was …

Relatively high tidal volumes, quantified as 12 mL/kg IBW or greater, cause un-physiological strain in the size-reduced ARDS lung.
WebbAccording to the manufacturer's recommendations, a target tidal volume of 8 cc/kg (based on ideal body weight) is selected. Initial settings are EPAP = 4 cm H2 O, IPAPmin = EPAP + 4 cm H 2 O, and IPAPmax = 25 to 30 cm H 2 O. If VT-BPAP is used in the ST or T mode, the backup rate and Ti must also be specified. WebbActually, in a 70-kg man, with respiratory system compliance of 50 mL/cm H 2 O and PEEP of 10 cm H 2 O, a tidal volume of 8 mL/kg yields a plateau pressure of 21 cm H 2 O and driving pressure of 11 cm H 2 O, both well below the currently accepted thresholds for VILI protection (30 and 15 cm H 2 O, respectively).
